@e-WM PATENT OFFICE ROBERT FRELAND, OF MONTREAL, CANADA,

IMPROVEMENTy IN APPARATUS FOR MAKING SOAP.

Specification forming part of Letters Patent No. 126,798, dated May 14,1872.

To all whom t may concern:

Be it known that I, ROBERT FREELAND, of

the city of Montreal, in the Province of Quebec and Dominion of Canada,have invented a new and Improved Apparatus for Making Soap; and I dohereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanyingdrawing and to theletters of reference markedthereon making a part of this specification.

My invention has for its object an improved apparatus for making soap sothat great economy, both in time and materials, is realized. The natureof my invention consists in making a cylinder or other suitable vesselin which the materials for soap are placed, and in which are placedrevolving' or rotating steam-pipes, connected with steam-shaft in such amanner that the steam enters the said revolving steampipes within thecylinder through the shaft at one end of the cylinder and is conductedthrough the length of the cylinder within the said pipes and may bedischarged at the opposite end, if desired; but this opening is designedmore for the purpose of discharging the water from the pipes made fromcondensed steam. By means of these steam-pipes the material for soap isbrought to a desired de-I gree of heat, and by the revolvingsteam-pipes,

which act as agitators and heaters combined, two purposes are served atthe same time. It further consists in the combination and arrangement`of a steamjacket upon the outer surface ofthe cylinder, in combinationwith the revolving steam-pipes', for the purpose of affording .a greaterdegree of heat to the material, if required.

To enable others lskilled in the art to make and use my invention, Iwill proceed to describe its constructionand operation.

Figure I represents a longitudinal vertical sectional elevation of myimproved -apparatus for making soap. Fig. II is a side elevation of thesame.

Letters of like name and kind indicate like parts in each f the figures.

A represents a cylinder or vessel, that may be made of any suitablematerials and of any desired dimensions or capacity, and may be variedand set in any desired or convenient position either horizontal orvertical. The space o, in Fig. I, indicates an annular steamchamber orjacket, provided as an auxiliary tothe steampipes for heating thematerials fromtwhich the soap is made. B represents a shaft, made hollowat each end and passes through and revolves orV rotates in suitablebearin gs in the cylinder. C represents a stuffi'ng-box, through whichthe said shaft passes at each end of the cylinder. D shows a pulley, bywhich the sha-ft is driven by any of the well-known powers. -t shows thesteain-way,

Within each end of the shaft, which connects' with the revolvingsteam-pipe E, in which any amount of pressure may be attained. Frepresents the induction-pipe or funnel, through which the material forthe soap is admitted to the cylinder, and G is the eduotion pipe,through which the soap is drawn from the apparatus. Il is a stop-cock,provided for the purpose of withdrawing the water made from steamcondensed in the pipes.

The operation of my improved apparatus is simple, cheap, and easy; landconsists in first filling the cylinder with the material and putting theshaft in motion. At the same time steam is admitted into the shaft fromthe generator, through which it passes into the steam-pipes, whichagitates the material at the same time it is being heated from therevolving pipes.

If these said pipes do not impart a sufticient degree of heat steam maybe admitted in the annular steam-chamber o; or it may be admitteddirectly within the cylinder and mingle with the surface of thematerial.

S is a faucet, to admit air into the cylinder while being filled withthe materials.

It will be understood that a proper steam connection is made at the endof the shaft at I, where the steam enters the shaft, with a pipeconnecting with the boiler.

By this apparatus soap is made in the most perfect and rapid manner.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

1. The combination of the revolving shaft B and steam-pipes E with thecylinder A, substantially as herein shown and described.

2. As an auxiliary to the steam-pipes E, the annular steam-jacket o,substantially as and for the purposes set forth.
